“…Chitin is a high molecular weight complex polymer and is generally insoluble in aqueous media and hence its uptake as such is not possible. Hence bacteria, especially Streptomyces (Brzezinska et al, 2013;Margino et al, 2010;Nagpure and Gupta, 2013;Prakash et al, 2013;Pradeep et al, 2014) and Bacillus (Kudan and Pichyangkura, 2009;Liu et al, 2010;Natsir et al, 2010;Waghmare and Ghosh, 2010;Dai et al, 2011) species, produce extracellular chitinases for nutritional purposes, in that they are able to utilise chitin as their sole source of carbon. Application of chemical based pesticides causes long-lasting adverse effects on ecosystems and human health.…”
